The marching band at Florida A&M University -- long a source of pride but more recently the subject of intense scrutiny because of a hazing death last year -- had serious academic problems, The Orlando Sentinel reported. Nearly 50 members of the 350 people in the band last year had grade-point averages below 2.0, the minimum required for participation in organizations such as the band. Twelve of those students had G.P.A.s of 1.0 or lower.
